Lots of things. You can use your Direct Payment to buy anything that makes your life better and meets your assessed needs. That can be anything from paying for membership of a fitness club, buying a laptop so that you can do your shopping on the internet or using it to pay to get you out and about to socialise. You can also use your Direct Payment to employ a Personal Assistant and pay for any associated costs or to buy support from providers such as care agencies. You can also buy care breaks and residential respite.
Usually, the things that you can spend Direct Payments on are detailed in your support plan.
